Lq4 ,ms4 in a 1971 240z Hey everybody
I recently put some new goodies on my engine and I want to know what everyone thinks she will put down
First of I had it dynoed last year
Previous set up
07+ lq4
Stock 317 heads
Ls1 intake
Custom 1 7/8 long tube headers to 3.5 collectors
3inch straight exhaust
Stage 1 monster clutch
85mm maf
02 ls6 cam
The dyno was dyno jet
It put down 368 rwhp and 379 rwtq
On the 2run the clutch went bye bye
So I decided to beef up the clutch and put down more power
So here is the new setup
Same lq4 with 1.5cc flycuts ,stock bottom end
.051 cosmetic head gaskets
Prc 2.5 ls6 heads milled .005
Texas speed ms4 cam
Same exhaust setup
7.4 comp pushrods
Ls7 lifters
Tr55 plugs
85mm maf
Aluminum flywheel
Stage 3+ spec clutch
25% undrive pulley
Ls6 intake
102 throttle body
Power steering deleted
And this is in my 1971 240z/fairlady ..she weighs 2590 without me in it and has 3.9 rear end welded
